FF Broken again after this latest update

[StevieB]

139.0.1 (64-bit)

Just updated. Cleared everything out as us usual, even re-booted Win 10 machine. Everything up to date.

FF is unusable like this.  It's either got a huge memory leak, which I have suspected for a long time. Or, someone has fluffed up with this latest update.

YouTube is just ridiculous waiting to load, heck, even Amazon takes a few minutes to load. Even just browsing the web is painful.

All I see are lots and lots of flashing text messages in the lower left corner with the usual waiting for handshake......waiting for images.google or Amazon etc etc etc

What the hell is going on with this browser. It seems as though it gets worse with every update rather than better !

And yes, I disabled all add-ons etc and still the same

However, switching to Chrome and all this goes away.

What's going on here?

I agree, everything is ridiculously slow, facebook marketplace messaging takes 10 seconds per "letter" !!! to appear.   Version 139.0.1 64-bit.    Validation is broken for apps and after 3 days still has not been reinstated.  Important functionality is broken.   I changed my passwords for one app, and then still couldn't in again after wards and it's incredibly slow, it was at zero upload speed, with 70 download this evening.  Super bad all round.   I would click on a link to arrow to the next photo in facebook account and nothing, it was taking at least 15 minutes for page refreshes to catch up.  All the major internet supplier outage pages showed nothing, so the Mozilla update sure packs a punch of bad karma.  Facebook games links time-out repeatedly and even during a game loses connectivity.  Shocking.

I also noticed some pages and extensions takes excessive amount of CPU and Memory when loading on the newest version (139.0.1).

At first, I thought it's Google's problem as it tries to intentionally cripples Firefox. But it affects all types of pages and extensions, not limited to Google or Youtube.

Without wishing to sound too harsh toward the devs, but, are these updates checked before they are released?

How do we get to the stage where an update cripples everything?

Whilst I am here, can I ask why so many updates, at times it seems as though there is an update almost every other day.

Also, why so many instances of FF running at the same time for one single web page open?

My record has been 17 instances for one google page. I seem to remember someone saying it was for performance and efficiency, but that seems the complete opposite to me at this rate.

Surely, a web browser should not be bringing our PC's to their knees!
